Ok, to avoid adding more comments:

1. Make sure you have the correct JSON data in your result string. Logging can help with tasks like that. Or maybe just use a Toast to just display the string to verify it's correct.

2. gv.setFilterText(s); will not cause any output. To display strings in the GUI you should use a TextView item that you put inside your layout, GridView in this case, and setText() on it.
